This can be especially so when very low concentrations of an analyte are being reported as clinically significant or when a reference range is very narrow. A good example is provided by the measurement of troponin in the diagnosis of myocardial infarction. Demands for more reliable and faster tests to detect heart attacks have driven the diagnostic industry to produce more sensitive assays.
